Title: Saccharification of cellulose.
IPC: C12P7/10
Filed: 1979-08-23
Abstract: A method for effecting saccharification of raw cellulosic material taken from any available source. The cellulosic material is hydrolyzed by immersing it in a bath of anhydrous liquid hydrogen chloride to yield usuable glucose and other products. The cellulosic material may be processed through one or more pre-treatment steps. each acting to enhance the yield of glucose and other products when the pre-treated material is subjected to hydrolyzation by anhydrous liquid hydrogen chloride. The raw material may first be immersed in a catistic solution which swells the cellular structure to render it more reactive and acts to solubilize the lignins and other compounds contained therein, these being washed away to provide a prepared cellulosic material. In another or second preparatory step, the material may be further prepared by subjecting it to a viscose process to produce a viscous solution of sodium cellulose xanthate in sodium hydroxide, from which solution the aqueous phase is separated, leaving a viscose intermediate. In the final step, the viscose intermediate is hydrolyzed by immersing it in a bath of anhydrous liquid hydrogen chloride.

Patent ES-8304386-A1 (ES)
Title: Switching circuit
IPC: H03K19/086
Filed: 1982-03-25
Abstract: A switching circuit includes a speed-up diode or transistor (Q3A Q13A) connected in diode-like fashion between a collector load resistor (12 24) of a switching transistor means (Q5/Q9: Q15/Q20) and a supply voltage terminal (41) for increasing the switching speed. The diode provides a turn-on delay, permitting the switching transistor to more rapidly discharge a parasitic collector capacitor (CA). The diode also provides a turn-off delay to more rapidly charge the parasitic capacitor (CA) when the switching transistor means switches to a nonconductive state. Another load resistor (10) may be connected in series between the collector of the speed-up transistor (Q3A) and the supply voltage terminal (41) to develop the output voltage of the circuit. In this case, the diode-connected transistor (Q3A) serves to buffer the switching transistor means (Q5/Q9) from parasitic capacitances of the output circuits and thereby further increase the switching speed. The switching circuit can be incorporated with a flip-flop circuit to increase its switching speed, which is of importance when the flip-flop is used for instance as a frequency divider in a phase locked loop tuning circuit e.g., for a radio or television receiver.
